Body weighted exercise shows the greatest change in muscle mass - Obadike Banded exercise is much more effective than free weights – Stoppani, Ph.D Banded and free weight exercise shows the same results - Calatayud Muscle activation only depends on the handle type – Rendos The length of the muscle contraction is the biggest difference in exercise - Fochi

My Proposal • Investigate the most popular and effective exercises: • body weighted (pull up) and resistance cable (lat pull down) exercise
• Taking place over a two week period in LMU’s Anatomy and Physiology Lab in the Summer of 2017 • The muscles strategically isolated in the experiment will be the latissimus dorsi and biceps brachii http://blogs.fasterskier.com/skis-strains-and-sprains/files/2011/11/lats.jpeg

Methods • Keep all variables consistent between the two exercises such as: • • • • • •
Resistance trained group Handle type Angle of Pull Number of repetitions Full extension Placement of Electrodes
• Use of EMG (electromyography) readings to quantify which exercise is more effective http://images.slideplayer.com/25/7999039/slides/slide_8.jpg
